SPECIFICATION forming` part 0f Letters Patent No. 693,299, dated `.February 11, 1902. Applieationfiled December 26, *1899. Serial No."741,633. (No model.)

To all whom, it may concern:

Be it known that I, ALEXANDER P. MOE- ROW, a citizen of the United States, residing at Elmira, in the county of Cliemung and State of New York, have invented certain new and useful Improvements in Bicycles; and I d0 declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to bicycles, and more particularly to a rear-wheelhub for bicycles adapted to support coasting and braking mechanism and provided with a braking-sur-Y face arranged intermediate the ends of the hub. Y

The improvement is designed for use with various forms of hub friction-brakes; and its primary object is to provide a hub with an overhanging brake-flan ge fixed to or integral with the hub and adapted to cooperate with a laterally-movable brake toarrest the motion of the bicycle by frictional contact between said brake and overhanging iiange.

The construction of the improvement will be fully described hereinafter, and defined in the appended claims, in connection with the accompanying drawings, which form a part of this specification.

In the drawings, Figure l is a longitudinal section of a bicycle-hub embodying the invention. Fig. 2 is a View in perspective of the form of hub shown in Fig. l, and Fig. 3 is a sectional View of a slightmodication of my invention.I

Referring to Fig. l, the reference-numeral l designates a sleeve or cylinder formed intermediate its ends, preferably at about its center, with an integral overhanging brakeiiange 2, terminating at its outer edge in an annular vertical perforated spoke-flange 3. The fiange 2, as shown in Fig. 1, is of bell shape, and its inner surface is adapted to constitute a braking-surface against which a brake is adapted to bear frictionally. The

hub l is also provided with an annular spokeflange 4, which is perforated for the attachment of spokes. The hub is formed with a series of beveled teeth or projections 5, forming annular beveled gripping or clutching surfaces for a laterally-movable element of the brake mechanism. Y

Instead of forming the entire hub in a single integral piece the sleeve l may be only of sucient length toconnect the spoke-flange 4 and the overhanging brake-flange 2, as shown in Fig. 3, andan independent sleeve 6 be employed having a threaded connection with the sleeve l of the hub and extending beyond the flanges 2 and 4. In this instance the annular projectionformed by the teeth 5 is formed inthe sleeve 6, 'as shown.

I claim as my invention-'- l. A bicycle-hub having a fixed hollow overhanging annular brake-ilange intermediate its ends; and an annularly-arranged beveled friction-surface'on the hub adjacent to the overhanging iiange and concentric with said brake-fiange.

2. A bicycle-hub comprising an exterior sleeve or cylinder formed at one end, with an 'integral overhanging iiange and adjacent to its opposite end with an annular spoke-dange; and an interior sleeve extending through the exterior sleeve and xed therein.

3. Abicycle-hub comprisinga sleeve or hollow cylinder formed with an integral overhanging annular brake-ange, having an upturned spoke-rim, a series of annularly-disposed beveled friction-teeth adjacent to said brake iiange, and an annularly disposed spoke-flange adjacent to the other end of the sleeve and concentric with the overhanging brake-flange.

In testimony whereof I affix my signature in presence of two witnesses.

ALEXANDER P. MORROW.
